Reasons for This new architecture has a number of advantages: Updates to a driver, such as a USB controller module, don't require a complete recompilation of the kernel; just the module itself needs recompiling. This reduces the likelihood of erro...

The installation of the kernel sources creates a file called README in the /usr/src/linux-2.6.5-1.358 directory that briefly outlines the steps needed to create a new kernel. Take a look at a more detailed explanation of the required steps. Make S...
